Question

6. Three resistances 3 ohm, 5 ohm and 6 ohm are given. Find out the magnitude of maximum equivalent resistance and minimum equivalent resistance which can be obtained.

Answer 1

Answer:

Maximum Equivalent Resistance=14ohm

Minimum Equivalent Resistance=0.7ohm

Answer 2

Answer:

maximum eq. resistance= 14

minimum eq. resistance= 30/21

Explanation:

We can get maximum resistance when we add this three resistance in series;

Rs = R1+ R2+ R3

Rs= 3 +5+6

Rs=14 ohm

for minimum resistance add all resistance in parallel

1/Rp = 1/R1 +1/R2+ 1/R3

1/Rp = 1/3 +1/5 +1/6

1/Rp= 21/30

Rp = 30/21 ohm
